This invention relates to that class of grainbinders in which a flexiblecord is applied around the gavel and is tied at its ends to form a band.The general principles of the machine v plate.

are analogous to those of a grain-binder for lar; but a new principle ofoperation, consisting in drawing the knot toward the gavel in tying, ispractically applied, as I will hereinafter describe.

The main features of my newmachine are as follows, viz:

First. A pivoted vertically-oscillating plate or frame, which supportsthe loopingjaws or head, the lower clamp, and the cutter, and in partsupports the tying-hook and the cam- This feature is shown in Figs. 5and 6, and, for convenience of description, I shall denominate it theframe of the tying mechanism.

Secondly. The upper clamps, which clamp and hold the two strands of theband separately above the tying mechanism during the operation of tyingthe ends of the band together and severing the tied band from theremainder of the cord.

Thirdly. The cam-plate, which oscillates the frame and operates all theworking parts of the clamping, tying, and cutting mechanism.

Fourthly. The loopingjaws or head.

Fit'thly. The tying-hook.

Sixthly. The lower clamp and cutter.

Seventhly. Asupplementary lever, which assists the looping-head inholding and looping the cord and presenting the loop properly to thehook. This last-mentioned element, together with the looping-head, thehook, and a flange on the block which directly supports the lower clampand cutter, all cooperate in the act of forming the loop and drawing thesevered strands through it to make the knot and accomplish the operationin such a manner that, as above indicated, the knot is drawn upwardtoward the gavel, thereby reducing the slack of the tied band to aminimum and making an exceedingly compact and closelytied gavel.

I have besides these elements an improved gavel-compressor, theconstruction and operation of which will be hereinafter described.

In the drawings, Z is that part of the binding table or frame whichdirectly supports the binding mechanism. A is the supporting-plate forthe two pairs of upper clamps and their connecteddevices; B, theoscillating frame or plate, hereinabove referred to; O, the camplate; D,the tying-hook; M, the loopinghead; I, the sup 'dementarylever; N, theblock which supports the lower clamps, and Y a 'ters Patent, or of anyother known and approof such channel.

priate form and mode of operation, and therefore constitute no part ofthis invention.

Referring now to the construction of the sev-' eral parts aboveindicated and shown in the drawings, and to the means by which theircooperation is effected to accomplish the work of tying the band placedaround the gavel, the following is a more full and exact descriptionthereof.

The plate A is of anyv suitable form, and is constructed with anopening, a, through which the needle operates, another opening, a, toallow the bindinghead to rise sufficiently while forming and tying theknot, andanother larger opening, a to accommodate the clamp arm or leverE, which is pivoted at e to a curved rim or arm, a, as shown in Fig. 3.The plate likewise has a depression,a in its surface to accommodate theplay of the pitman E, which operates the upper clamps. The opening a ismade preferably in the L form represented or an equivalent form, and isguarded on one side by a vertical rib or flange, of, and on two othersides by an angular vertical rib or flange, a The flanges a a do notjoin, but are separated by a narrow space or channel, a7, through whichone strand of the band extends when the binding operation is inprogress. The-end of the flange a at this space is abrupt, but the endof the larger flange, a is beveled down, so as to guide the cord downinto the channel.

A friction-roller, a may be arranged at the rear edge of the opening ato diminish the friction of the needle against the plate;

The fixed jawsot' the two upper clamps are shown at e 0 the former beingoutside of the area inclosed by the ribs a a, and immediately in frontof the channel a, and the latter within such area and immediately inrear The movable jaws of the upper clamps are shown at 6 6 the formerworking in connection with the fixed jaw 6 outside ot theneedle-opening,-and the latter workingin connection with the fixed jaw ein the side wall of the needle-openin g, an aperture 6 being madethrough the flange a to allow the jaw to pass through and cross saidopening. The jaw e is provided with a projecting spur, e, which, whenthe jaws are closed, enters a hole in the rib u behind the cord andprevents the latter from escaping from between the clamping-jaws.

The movable portion of the upper clampingstructure consists of anassemblage of plates, 6 6 6 all pivoted to a common center, 6', anddesignated as a whole by the letter E in the drawings. Of these threeplates the middle one, 0, is connected directly to the pitman E, whichactuates the clamps. The upper one, 0 slides laterally to a limitedextent on the middle one, a, and is provided at its outer end with aright-angled arm terminating in the jaw e, and the lower one, a, slidinglaterally under the plate 0 to a limited extent, also is provided at itsouter end with a right-angled arm terminating in thejaw 0 A small rubberspring, 6 interposed between the middle plate'and a flange on the plate0 gives the jaw e an elastic or yield- I ing action againstitscorresponding fixed jaw 6, while a similar spring, 0 interposed in ananalogous manner between the plate 0 and a flange or shoulder ofthe'plate, e renders thejaw e elastic and yielding in its action. Theindependent action and elasticity of the two clamps adapt them to anyinequalities in the cord, and .prevent any improper adjustment of themfrom severing the cord, breaking any of the parts, or obstructing theaction of the machine. The outer end ofthe plate, 0 rests upon adepressed flange, 6 of the plate A, and is guided by said flange and bythe opening in the rib a, through which its.

jaw extends. The outer end of the plate 0 lies under a spur, eprojecting from the plate 0 andis thereby properly held down to itswork.

It will be observed that although the body of the plate 6 lies under theplate 0 its outer and extends up beyond the end of said plate a, so asto bring the two jaws, 0 e at the same level. By the movement of thepitman E the middle plate, 0 is oscillated back and forth, and the twojaw-plates, 0" 0 are carried back and forth simultaneously with'it, thisprovision of the three plates being merely to give each jaw anindependent spring action.

The force of the spring movement of the jaws. may be regulated byadjusting-screws e at the rear edge of the plate 6 which pass in andbear against the two springs above described.

The plate A with the devices supported by it is arranged under thebinding-table, which covers all its working parts except thefrictionroller, the upper edge of the rib a, the fixed jaws, and theends of the movable jaws when closed. An opening in the binding-tabledirectly over the opening a permits the needle to pass up and down. Thehorizontal arrangement of the upper clamps enables me to bring anextended clamping-surface to bear upon the cord between the gavel andthe tying mechanism without separating the tying devices too far fromthe gavel, so as to leave too much slack in the tied band.

The frame B, pivoted to the bar Z at z, is constructed in the form shownin Figs. 5 and 6, or the equivalent thereof. At its front edge it isprovided with a narrow dependent flange, l), and two longer flangedarms, I) b, which support the cam-plateand hold it in proper relation tothe frame, as seen in Figs. 1 and 2. It is further provided with twodependentlugs or bearings, Z1 b ,which support a rocking shaft G, andbetween the said bearings'the frame is cut away, as shown at 11 toaccommodate the rocking of the shaft and its connected mechanism. Itisfurther provided at its outer end with a curved, slotted, and inclinedguide, I), which guides and limits the movement of an arm, g, attachedto the shaft for the purpose of rocking the latter and imparting to it alimitedlongitudinally-slidingmovementin its said bearings.

The cam-plateG is arranged under the frame B in the supports 1) b, andis provided with three slots, 0 c o as shown in Fig. 13. A strong headedbolt or stud, 2*, projects from the bar Z through the slot 0 for thepurpose of assisting to hold and guide the cam-plate. The cam-plateO andframe B are thus so connected together by the flanged arms b andsupported by the two studs 2 2 that they oscillate together on thepivots z, and are swung up and down by the action of the stud zin thezigzag slot 0 of the cam-plate; but it will be observed that the frame Bhas no sliding longitudinal movement, while the cam-plate has such amovement effected by the pitman that connects to the wrist-pin y andlimited and controlled by the form of the slotc. The camplate is furtherprovided with a curved slotted arm, (3, containing a slot, 0 c, of whichone end,c ,is straight,and the other end,c,curved and spiral, as shownin Figs. 13 and 14. The end of the arm 9 of shaft Gr extends into theslot 0 c, and as the cam-plate is reciprocated by the wrist-pin Y theaction of the guide-slot 0 upon the arm 9 rocks the shaft G and theparts supported thereon, while the effect of the inclined guide b is tomove the shaft lengthwise when it is thus rocking.

N is a small block or casting, rigidly fastened to the shaft G androcking therewith. In a suitable bed or recess contained within it Iarrange a pivoted bar, a, having a spring, 22, beneath its free end toforce it outward with an elastic yielding pressure. At one edge of t thebar n. is a curved projection, n constituting the lower clamping-jaw. Alittle above the bar it a stout armor platemfiextends from the block Nbackward and downward to a point-directly in horizontal line with thejaw 12?, where it terminates in a flange or wide flat head, a, one edgeof which projects in toward said jaw and operates as the fixed jaw ofthe clamp. A flange, n extends from the lower rear edge of the block upagainst the lateral edge of the flange or head a, as shown, for thepurpose of properly guiding the cord. The two jaws n n are held togetherwith considerable force by the spring n. An-openingexists above andanother below them, as shown in Fig. 20, to accommodate a sliding plate,S, which serves to tuck the cord in between the clamps n n, and insuretheir proper hold upon it. t

The sliding plate is provided with a slot, 8, which bestrides the jaws n12, leaving the bifurcated ends of the plate to pass into the openingsaforesaid. The plates 12 S are made of steel, and the upper fork of S isprovided with a sharp edge, 8, (see Fig. 1,) which, co-operating withthe sharp edge e of the plate a" adjacent to the opening in said plate,through or into which the fork extends, serves to sever the cord belowthe knot. The end of the bifurcated plate which acts as a cutter titsclosely into the opening above described, so that the cord mustnecessarily be severed by its edge acting in connection with the edge ofthe opening, and even if the edges wear away or become dull the cordwill continue to be severed by them, because it cannot pass throughbetween the surfaces of the parts S a The plate S is guided by lipsorflangess attached to and projecting from the block N, and is actuatedby a toggle-lever, H.

The connection between the toggle and the plate is effected by a groovedblock, lusliding on the shaft G, the end of the plate S having a flange,sflwhich rests in the groove, and therefore communicates any movement ofthe toggle to the plate S. The toggle being mounted loosely on the shaftG would be liable to rock with the shaft if it were not heldin positionby an arm, H, extending down alongside ofit from theframe B. The toggleon the sideoppo site to the arm H is provided with a pin or stud, h,which works in the slot c of the camplate. When thestud descends intothelower inclined end of the slot it bends the toggle or bringsits armsto asharp angle with each other, thereby drawing the plate S away fromthe clamping-jaws. When the stud ridesup on the horizontal floor of theslotit nearly straightens the toggle-arms, thereby projecting the plateS toward the clampingjaws and causing it to engage with the cord andforce thelatter between said jaws, so that they will grasp and hold itfirmly. A further movementofthe plate S toward the jaws causes the sharpedges 3 s to come together and sever the strands of cord between them,and this further movement is effected by causing the stud h to ride upover IIO abeveled switch-bar, K, and thereby straighten and after it haspassed a spring, k, (shown in dotted lines, Fig. 13,) depresses the headagain upon the floorof the slot. When the cam-plate reaches the end ofits movement in said direction and returns, the stud rides up over thehead, and thus causes the cutters to sever the cord after the loop isformed and just before the tying-hook commences to draw the ends of thecord through the loop.

The looping and tying mechanism is constructed as follows: v

M'is a block attached to the upper side of the frame B at the points mm, and provided with two projecting lugs, m 'm, at its upper and lowerrear edges, and with a deep straight groove or recess, m extendinglongitudinally in its rear side between said lugs.

M is a bar, pivoted to M at m and extending in the groove m to theopposite end ,ofthe block, where it is provided with a projecting plateor head, m that strikes the side walls of the groove and prevents thebar from resting on the bottom of the groove, thus forming a smallopening, 25, longitudinally through the block between the bar M and thebottom of groove m as shown in Figs. 16, 17, and 21. The ends of theblock M andbar M are fitted closely to each other and are beveled on thelower corners. The rear corner is also beveled, or, rather, it isslightly concaved, as

shown at W.

rests upon the top of said block, while the exiremity of such flattenedinclined part projects upward and backward from that point in the formof a horn. row channel or space between said parts U and M M when theyare closed together, through which the cord extends ata certain stageinthe looping and tying operation. The three parts V M M are so fitted,adjusted, and smoothed off as to present, when closed, almost theappearance ofa single rounded head having a slot or opening, t, throughit longitudinally.

' Directly in front of the block M, slightly above it and between it andthe bar Z, extends a lever, I, pivoted at z to a pivoted plate or bar,J, and provided with a retracting-spring, t". An arm, 6 projecting underit froui the. bar Z, holds it up to its proper position, or any othersuitable device maybe substituted in place of the arm 1' for the samepurpose. This lever, near its free end, is twisted so as to present itsflat side in a vertical plane and ening-head, i which, at a certainstage of the operation, moves back against the front edge The concave mforms a nar-v ot the incline V; and it is further provided with a smallsharp spur, a, which at the same time overlaps and bears against theouter inclined face of the part V, as shown in Fig. 17.

The lever I is connected by a rod, L, to an arm,U,on the lever U,whereby the partsVv are caused-to move toward or from each other on oneside of the track, passing around said switch Pin a manner which will beunderstood by skilled mechanics without further description.

The tying-hook D is supported at its rear end by lugs d d, projecting upfrom the side or end of the cam-track (),and it is provided with aspring, 01, adjusted by the nut 61, which spring allows it to yieldslightly in a longitudinal direction while the cutting mechanism isoperating, but the extentof its yielding is limited by a nut, d whichmay be adjusted on the bar. When the nut comes in contact with thebearing-lug d the effect of the spring willend and the hook will bedrawn by a positive unyielding force. From thelugs d ditextendsthrough aguide, d and passes into the space between the block M and the bar Mhereinabove described. A flat spring, at, resting against the bar M,behind the lever U, presses said bar against theside of the hook with ayielding force, so that when the hook draws the severed end of the cordinto the head the said severed end will become clamped between the bar Mand the side of the hook-bar with a force sufficient to draw the knottight; but while so the cord, but not strong enough to break it, nor

toprevent itfrom drawing gradually out from between said parts. Toenable the hook-bar to clamp the cord more strongly without using aspring of undue force the side of the said bar may be roughened.

The pitman E is connected to a lever, It, pivoted to the stud z. A stud,r, on the lower end of the lever B, travels in the slot 0 of thecam-plate, thereby actuating the upper clamps at the proper time and inthe proper manner. The form of theslotcis clearly shown in Fig. 13.

The operation of these various devices is effected, as above stated, bythe reciprocating cam-plate, and is asfollows: The cord having been dulysecured between the lower clamps in the usual manner and the needleraised, the gavel is formed upon the binding-table and the needle isready to descend. At this juncture the cam-plate will be at its extremeleft-hand movement toward the end a of the bar Z; the hook D will bedrawn back from between the block M and bar M; the stud 9' will be inthe right-hand lower end of the slot 0, and will hold the two upperclamps open; the stud u will be at the extreme right-hand end of thecam-track 0, and will hold the pin 'Ufllld inclineVaway from the head MM; the stud h will be at the extreme right-hand end of slot 0 and willhold the plate S back away from the jaws a n; the stud or arm 9 willbeat the extreme right-hand end of the cam-guide slot 0 c, and will holdthe block N with its face in a Vertical position, so that the cord canpass down between the endof plate S and the edge of the lowerclamping-jaws; and the stud 2 will be at the right-hand end of slot 0,and will hold the cam-plate and frame B depressed away from the plate A.The needle will now descend,carryin g the cord around the gavel and downthrough the plate A and below the lower clamp, and when in that positionthe camplateO will begin to slide toward the right hand or toward theend 2 of the bar Z. As the first result of this movement the toggleleverH and the lever B will simultaneously close both the upper and'lowerclamps, causing them to grasp and hold the cord tightly, thelowerclampsholdingboth strands, and each pair of the upper clamps holding a singlestrand independently of each other. The stud a will now strike theswitch P and ride up thereon, closing the part V toward the ends of thehead M M so as to grasp both strands of the cord between them and forceit against the side of the head M M. the spur n will advance and assumea position at the left-hand side of the cord, as shown in Fig. 17, andbear against the incline V. The stud a will now reach the inclined partof the slot 0, and simultaneously the stud y will reach the curved partof the slot 0 c, in consequence of which the cam-plate with all itsattachments will begin to rise, and the block N with its attachmentswill begin to turn; As the head M M V rises the pin a will slide uponthe incline V, engage with thefloord and carry it down over the convexend of the head,the

block N still rising and rocking over toward the forming loop. Thepin vcontinuing to act against the cord and the head continuing to rise, thestrands held by the pin will be brought below the opening in the head,and the pro- 'ecting lip or flange n of the lower clamp will by thistime have rocked over so far as to strike the other part of the cord andcarry it across the strands held by the pin '0, thereby forming a loop.At this instant the tyingliook willbe thrust through the loop thus formed, and the cam-plate will arrive at the extreme right-hand limit ofitsmovement. The camplate will now move to the left; the hook D will seizethe crossed strands and begin to draw their ends through the loop; thetoggle will immediately be straightened and cause the cord to be severedbelow the loop, leaving Simultaneously the ends of the looped portionfree; the levers U and I, by the operation of the stud it against theleft-hand end of the switch I, will be opened, leaving the entire loopfree, except the strands held by the hook; and the hook, continuing torecede, will draw the severed ends ofthe cord through theloop, form theknot, and tighten it in the manner above described. The loop beingentirely free the knot will draw upward toward the plate A, so as toleave the minimum of slack in the tie-band. The continued movement ofthe cam-plate in the same direction opens the upper clamps and leavesthe bound gavel ready to be discharged from the machine. It will beobserved that the hookD is arranged upon a support in line with butindependent ot'the head,so thatwhen it is retracted it will drawentirely out,-leaving a clear space between them, and that when it movesforward again its side will come in contactwith the edge of the head atthe bottom of the bed or groove in and scrape or slide against or overthe same. This is for the purpose of causing any filaments of the cordadboring to the hook, to be scraped off ofit at the rear end of the headand be discharged from the machine, or, in other words, of cleaning thehook at each operation.

While the above-described improvements are capable of use in connectionwith various kinds of binders, they are, as here shown, especiallyadapted to that class of binders in which a section of the binding-tableis movable for the purpose of more properly gathering and condensing thegavel. In binding grain the condensing and compacting of the gavel is anexceedingly important matter, and, so

far as I am aware, no machine has ever been constructed which wouldperform that part of the work with completely satisfactory results; butthe gavels have always been left somewhat loose and the band more orless slack. Now, one object of my present invention is to perfect thatpart of the operation; and to this end I employ, in addition to theordinary compressor, a supplementary compressor, which exerts a rollingaction upon the gavel, where- IIO by it not only presses on the grain,but rolls it together and rolls the gavel over toward the needle whileso pressing it. This rolling action is'intended to imitate the operationof a skilled workman in binding grain by hand, it

(Q may be constructed with a coil, g to increase its torsional springforce. In. connection with this rod another rod, Q, is arranged Themeans by which I at the upper edge of the bar Z, said last-mentioned rodbeing supported by a bearing, g aflixed to the bar Z, and by a loop inthe end of the arm (1 The rod Q should be made of some springy material.After passing through the loop at the end of the arm 9 as described, itis bent upward, as shown at (f, and then bent around and back into theform of a long arm, g, which extends considerably below the lower edgeof the bar Z and always below the surface of the binding-table on whichthe gavels are formed and bound.

The rod Q q may be re-enforced by a lateral rod, q, if preferred, so asto enlarge the surface which-acts on the gavel, and when'constructed inthis form the ordinary gavel-compressor, if any is employed, shouldpreferably be arranged to exert its action on the gavel at a pointbetween the arm g g and the re-enforcing arm 1 said two arms beingarranged far enough apart to accommodate its movements.

In the operation of the machine the gavel is formed on thebinding-table, and is in part condensed by the operation of the movablesection of the table, (when such table is used,) in part by the ordinarycompressor or other device employed for compacting the gavel, andin-part by the needle and band; but to supplement the action of allthese parts, or so many of them as may in any machine be used, the rod Qis caused to rock in its bearings, so as to bring the arm q q q" upagainst the front side of the gavel and compress the latter back towardthe needle. The rod Q then continuing further to rock in the samedirection, the torsional arm (1 springs out, allowing the arm Q5 q" tohear more and more on the top of the gavel and roll the latter under it,so as to condense it by the rolling action,as above described; or, inother words, the compressor Q Q so acts to cause its effective point ofcompressing contact to be applied first to the front side of the gaveland in a horizontal direction, and then to travel up over the gavel andend by applying said force on the top of the grain in avertically-downward direction, the result of which movementis that thestraws are rolled or worked together much more compactly than they couldbe by a force or forces acting uniformly in the same directions. The rodQ is provided with a crank-arm, g, by which it may be rocked by aconnecting-rod extending to any suitable part of the operating machineryof the machine. When the gavel has been bound the arms g g g drop backto a horizontal position, the long end, g swinging in under the machineout of the way and the gavel is discharged over the horizontal upperside of the arms g Q7. When a new gavel is ready for compression thearms (1 q again rise'between the old gavel and "the new one, thus actingas a separator between them. If the end g were made so short as to riseabove the bindingtable, it might, in commencing to descend, catch in theold gavel or straw on the outer edge of the table; but by making it ofsuch length as never to come above the table it cannot catch, but willassist in pushing the old gavel off of the table.
